I bought a used InlinePro Stage 1 kit a couple months ago, and I'm ready to put it into my AP1. This would be my setup.

InlinePRO T3/T4 Cast Iron manifold
Precision 6265
InlinePRO Blowoff Valve
InlinePRO 2.5" charge pipes
InlinePRO 3" downpipe
InlinePRO Couplers and clamps
InlinePRO 600hp intercooler
Tial MVS wastegate
InlinePRO Oil Feed kit
InlinePRO Oil Return kit

RC 550 Injectors
3" Test Pipe
70MM Dual T1R exhaust
255 Walbro Fuel Pump
AEM EMS 1052

I know I would probably want to get bigger injectors or a more free flowing exhaust, but I'd like to get some feedback on actual whp numbers and at what boost level. I'm also up for suggestions BESIDES "get a better turbo kit". Thanks in advance!

 

looks like you are already aware of the injector and exhaust problem
with 550cc injectors, you will be limited to about 400whp
to hit 400whp, you will be at 12-13psi with that turbo

 

near 400wp would be perfect for me. is 12-13 PSI still considered safe for a stock motor? I know I'll probably want more later down the road, that power level should be fine for now.

 

You will be fine with that power level pending your tuner.

 

You'll make 400whp with thit kit no problem. Especially with that turbo.

 

That's a monster turbo for 400whp.. I would hate that powerband, get something smaller like a 5758

 

I'm guessing that's why this setup comes with a dumptube. previous owner claimed full boost at around 4500RPM.

 

Thos 6265 are great turbos they have Garrett guts it is big for your goals and will be easy to keep out of boost for DD use

The kit is very capable, but you will be better off upsizing the fuel flow. I made 515whp with the old 5865 precision turbo on this kit and could have made more if i had more fuel at the time. This was on e85 btw. Pump gas will be less.

 

what injectors/fuel pump did you have? and at what PSI?
